Mandriva Update for dhcp MDVSA-2012:115 (dhcp)

Published: 2012-07-30 05:52:50
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:A/AC:L/Au:N/C:N/I:N/A:C

Summary:
The remote host is missing an update for the 'dhcp' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
dhcp on Mandriva Linux 2011.0

Recommendations:
Please Install the Updated Packages.

Technical Details:
Multiple vulnerabilities has been discovered and corrected in ISC DHCP: An unexpected client identifier parameter can cause the ISC DHCP daemon to segmentation fault when running in DHCPv6 mode, resulting in a denial of service to further client requests. In order to exploit this condition, an attacker must be able to send requests to the DHCP server (CVE-2012-3570) Two memory leaks have been found and fixed in ISC DHCP. Both are reproducible when running in DHCPv6 mode (with the -6 command-line argument.) The first leak is confirmed to only affect servers operating in DHCPv6 mode, but based on initial code analysis the second may theoretically affect DHCPv4 servers (though this has not been demonstrated.) (CVE-2012-3954). The updated Linux Distribution Packages have been upgraded to the latest version (4.2.4-P1) which is not affected by these issues.

Detection Type:
Linux Distribution Package

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
